STONE METEORITE SPHERE - INTERNAL STRUCTURE OF A STONE METEORITE REVEALED
H6
Sahara Desert, Algeria
As described in the "meteorite steak" offering (see previous lot), to avoid confusion, meteorites are named after the nearest city, county or geological feature in proximity to the point of recovery. When there are no such landmarks, such as in the middle of a desert, meteorites are numbered. This is an example of NWA 099 - the 99th meteorite to be classified originating from the Northwest African (NWA) grid of the Sahara Desert. As it is less exotic as meteorites go, some NWA 099 specimens were subdivided and fashioned into spheres - something that would never occur otherwise given the amount of material lost in the grinding and fashioning processes. A variegated matrix with hues ranging from cream to chocolate is plainly evident, and a dappling of metalflake - diagnostic in the identification of chondritic meteorites - is seen throughout. 79 mm in diameter and 925 grams (2 pounds).
